Imaging of the Temporomandibular Joint.

Temporomandibular disorder (TMD) is a common musculoskeletal condition that causes pain and disability for patients and imposes a high financial burden on the healthcare system. The most common cause of TMD is internal derangement, mainly secondary to articular disc displacement. Multiple other pathologies such as inflammatory arthritis, infection, and neoplasm can mimic internal derangement.

Clinical Application of Artificial Intelligence in PET Imaging of Head and Neck Cancer.

Applications of "artificial intelligence" (AI) have been exponentially expanding in health care. Readily accessible archives of enormous digital data in medical imaging have made radiology a leader in exploring and taking advantage of this technology. AI-assisted radiology has paved the way toward another level of precision in medicine.

Recombinant activated factor VII in a patient with intracranial hemorrhage and severe thrombocytopenia.

Hemorrhage in patients with hematologic malignancies is often difficult to manage as many of these patients also have coagulopathy and thrombocytopenia of varying severity. Recombinant factor VIIa is a FDA-approved agent for management of bleeding in hemophilia patients with inhibitors. Use of recombinant FVIIa has also been used as a last resort in various clinical settings such as trauma, alveolar hemorrhage, gastrointestinal bleeding, and intracranial hemorrhage for control of bleeding with variable outcomes.

Syphilitic Aortic Aneurysm: A Rare Entity in the Era of Antibiotics.

A thoracic aortic aneurysm is a rare entity of tertiary syphilis in the era of antibiotics. The diagnosis of the aortic aneurysm due to tertiary syphilis may be challenging due to deceptive clinical presentation and rarity of the disease in the western world. We report the case of a 59-year-old man, who presents with worsening shortness of breath and was found to have a large ascending aortic aneurysm on computed tomography angiogram (CTA) of the chest.

Fetal MR imaging in urogenital system anomalies.

Fetal magnetic resonance imaging (MRI) is an important adjunct to ultrasound in evaluation of fetal urogenital system. While, ultrasound remains the primary modality, MRI helps in more complicated cases or where ultrasound is limited due to technical factors such as poor acoustic window. The goal of this article is to review the common fetal urogenital anomalies and their imaging manifestations on ultrasound and MRI, and discuss how MRI adds diagnostic value.

Risk factors leading to hospital admission in Iranian asthmatic children.

Background: Asthma is one of the most common chronic diseases in the world, leading to an increased rate of hospitalization. We performed this study to better understand the factors leading to admission among asthmatic children.

Methods: We performed a study among asthmatic children in a referral hospital for asthma and allergy in Tehran.
